Please do not steal this guide for your website without first asking me. Note this is my second attempt at a guide, so it won't be perfect. Any help from others will be credited in the guide.

Decided to try using spoiler tags to make the guide easier to find what you are looking for. I wasn't sure if I should do it for the sections of achievements in-case someone just wants to search for the achievement name with CTRL + F.
Let me know what you think of using the spoilers, if it makes it look nicer, or if I should get rid of them.

Introduction:Joe Danger feels like a platformer version of Trials HD, and just like Trials it is highly addictive and fun.

It costs 1200($15) and is worthy every penny in my opinion. I had countless hours of fun comboing for high scores (got one around 361 million putting me at 2nd in the world currently) like I did back in Tony Hawk Pro Skater 3.

Gametypes:There are 3 different gametypes that contain achievements.
--Career:This is your bulk of the game, and where you will earn most of your stars and pro medals.

--The Lab:This is kinda like a secondary career with a partial tutorial for Sandbox mode in the way of moving pieces to complete the levels. You can also earn your stars and pro medals in here.

--Sandbox:This is where you create levels, one of the achievements you get by sending your creation to a friend.

Mop-up:There is only one achievement which doesn't fall under the categories above, and that is receiving a level from a friend. You CAN send it from an xbox live silver account to yourself if you don't have any friends that play the game.Conclusion:This game is fairly easy and highly addictive, you will have countless hours playing through this. Sometimes it can get aggravating, but just stick with it and you will prevail!

1.) ALWAYS use the left and right triggers to control joe in the air. This will help you avoid overshooting stars, coins, and Danger letters.
2.) Keep your boost bar FULL.....you never know when you'll need some momentum or airtime. The best way to refill your meter is to wheelie on straight aways or flip during jumps.
3.) Hold the X button before you hit a "spring" or bouncing pad and release it as soon as contact is made..this will help elevate you higher and is useful for reaching hidden stars.
4.) Remember the wheelie counts as a trick and keeps your combo active....master and use this to your advantage.
Hope these tips help!!!

Combo stars are the ones you get for doing 1 combo in the level only. If you fail a combo and are still at 0 points, you can start a new combo and that will count as 100% combo...I don't think it's supposed to work like that, but it does

Speed Demon! 5
Get a Time Star

See All the time in the world!

All the time in the world! 10
Get 15 Time Stars

Time stars are the ones you get for completing the level in a better time than is shown on the loading screen when you start it, or on the screen when you finish a level.
Sometimes it is easiest to get this by jumping portions of the map that contain items or choosing the fastest track when you have a choice.

Get 5 Target Stars

Target stars are the ones that you have to land on each target in the level. Boosting with A or jumping with X is sometimes needed.

Money Grabber! 10
Get 5 Coin Dash stars

Coin Dash stars are only on the coin dash levels, where you touch a red coin to start a timer with gold coins to grab. Just be speedy and you should have no problem getting this.

Ninja Stars! 5
Get 4 stars in one run

Find a level that has at least 4 stars on it, and make sure you get 4 stars in one run through of the level. Most SE Pro coins require 4, so you will eventually get this if you go for the SE coins.

Collector 10
Collect all Pickups on 8 levels

Find any level that has the pickup star symbol (looks like the pic of the achievement) and make sure you collect them all. It isn't always stars, for example, sometimes dinosaur eggs.

Detective! 10
Find 3 Hidden Stars

Hidden Stars are the ones that are hidden in the level. All hidden stars are shown in the stars you can get for the level, so you can tell if it has them or not. They like hiding them on tall buildings.

Receive 1 level from a friend

Have a friend send you a level they created in sandbox. You can use a secondary silver account to send or receive the level, so no trading needed.

Mega Combo! 10
Get a x100 combo

This can be done in any game mode, you just have to get a x100 combo, the way you tell is after the score in the middle of the screen is an x and then a number, that number is your current combo. If you need to boost the combo on straightaways you can hop and tab LB or RB.

NOTE: If you are having trouble with this, you can do it in a created level, it won't unlock when you hit x100, but if you quit out and send a level to a friend or do any level in career or the lab, it will unlock then.

Added: All SE pro coin levels and unlocks.
Added: Spoiler tags for Sections as a test to see if people like it better than a wall of text
WIP: Still need the last colored achievement image for getting all stars in career mode
